Sub-Hertz Spectral Analysis of Polarization of Light in a Transcontinental Submarine Cable
Abstract
We report on a field-trial over the Curie cable connecting USA to Chile. We detected
environmental changes through measurements of polarization of light. Seismic waves stemming from
moderate-size earthquakes caused perturbations in the 0.5-3Hz range, suggesting that transcontinental
cables may be used to detect earthquakes.
